It would seem logical to name them for where they are and what they do. “Bathroom motion sensor”, “Bedroom lamp”, etc. However, I’ve found that, if it can move, it ends up moving sooner or later. My “bathroom” motion sensor is now in the upstairs family room, for example.
I use room_object. It’s easier to find the to make automation and for my dashboard. I tried not to moove them to much and I don’t have a lot of object so it is fine. Most of them don’t moove anyway, lightbulb, vacuum, speaker. (I messed up at the beginning with the naming of my light by not naming them correctly and it is an error that I still have to deal with. (And it’s a pain in the ass)
